Part Number: ADS42JB69
I am trying to use the load impedance of the differential input lines of this part in a Keysight ADS simulation. What would be the best way to set this up? I see no convenient circuit model is given, like other TI device datasheets have. Thanks.

Thanks. Any update?
In reply to Niral patel:
I've checked and there aren't any additional model details available for the analog inputs of this device. The only information I have found is that in Section 10.2.2.1 of the datasheet.
I recommend you utilize one of the input matching networks shown in Figure 114 and 115 as needed for your particular signal frequency case.
I recommend the following:
1) From Figure 112 generate a curve fitting equation for the resistance as a function of frequency.
2) Using that equation create a frequency dependent impedance value in ADS. I have not done this myself, but found this discussion on-line that looks like it does what you need.
